Improvement in attaching crosscut-saws to their handles



UNITED STATES PATENT OFFICE.

DAVID BEARLY, `OF NEW CASTLE, INDIANA.

IMPROVEMENT IN ATTACHING CFIOSSCUT-SAWS T0 THEIR HANDLES.

Specification forming part of Letters Patent No. 50,676, dated October 31, 1865.

To all 'whom fit may concern Be it known that I, DAVID BEARLY, ot' New ings, and to the letters ot' reference marked thereon, making a part ot this specification.

The nature of my invention consists in the shape and construction of the hinged fastening, arranged and combined with a button or knob on the handle to tighten the saw firmly to the handle.

Figure l represents the saw; Fig. 2, the hinged fastening; Fig. 3, the handle.

A represents the saw-blade, with fastening B on each end.

C is the hinge ofthe fastening.

DDare screw bolts and nuts, thatare passed through the fastenings of the saw to tighten the saw and hold the handle firmly. The fastenings B are rounding near the hinge, so as to fit closely on and around the tenen of the handle. The ends are dat and squarefso as to tit tightly to the saw when the screw-,bolts are passed through the apertures in the ends of the saw and the apertures in the fastenings,

so that the nuts can be screwed tightly. Flanges E E are at each end ofthe t'astenings, so as to prevent the saw t'rom passing any farther while sawing.

A turned knob, Gr, is at the lower end of the handle, to prevent the saw from slipping' oft' the handle and to take the place of wedges, that have been commonly used to secure the handle to the saw-blade, but were always working loose and falling out.

Another advantage ot' `these fastenings is, not only securing the handle firmly to the saw, but easily removed when required,'so as to draw the saw through the log. In case the saw gets bound I'ast by the log, the screw-boltsSv` are quickly unscrewed at either end and the, fastening B and handle removed, when the saw that was bound by the log can be immediately drawn out.

What I claim as my invention, and desire to secure by Letters Patent, is-

The construction of the hinged fastening B, in combination with the knob G, as herein de scribed, and for the purposes set forth.

DAVID BEARLY.
